All models were handmade, and featured a recess behind the lower horn to make access to the upper frets easier.
Both electric models were produced with bolt-on necks, however there are examples of neck-through construction.
The bolt-on models had an angled neck plate to further facilitate better access to higher frets.
The BE-140 acoustic featured a piezo pickup in the bridge and a 21 fret cut-away body style.
Most of the Mason Bernards have plain ebony finger boards, however there are some special player guitars that feature inlays.
